Choosing the Right Heating Method: Electric vs. Steam vs. Hot Oil — Limitations and Fit
Platen heating is one of the most important decisions in a hydraulic press specification, and it is one that often gets settled quickly based on familiarity or facility preference rather than a systematic evaluation of what the application requires Electric heating, steam, and hot oil are the three primary methods used in hydraulic press platen…

Press Styles Explained: Four-Post vs. C-Frame vs. Slab-Side — How to Choose
Press frame configuration is one of the foundational decisions in a hydraulic press specification. It has downstream effects on how the press performs, what it can accommodate, and how it fits into the production environment. Accudyne engineers and builds hydraulic press systems across all three frame styles in both up-acting and down-acting configurations. Four-post, C-frame, and slab-side are the three…

From Part/Mold to Press: What Information Helps a Press Builder Design the Right System
A hydraulic press is rarely designed around tonnage alone. The part geometry, tooling design, production requirements, and facility limitations all influence how the system should be engineered. In many cases, customers begin the quoting process knowing the product they need to manufacture, but not necessarily the press configuration required to support it. That is normal. A large portion of the engineering…

Compression Molding Presses: When They’re Used and What Matters Most in the Specs
Compression molding is one of the most widely used processes in rubber, polymer, and composite manufacturing. It is a direct process: material is placed in an open mold, the press closes under controlled force and temperature, the material flows and cures, and the finished part is removed. The simplicity of the basic sequence makes it…

Composite Molding Presses: What Engineers Should Ask For (and Why)
Composite molding presses are often specified around tonnage and platen size first, but those values alone rarely determine whether the system will successfully support the manufacturing process long term. Part geometry, tooling design, cure requirements, pressure distribution, and thermal control all influence how the press should actually be engineered. In many cases, the press itself becomes part of…

How to Spec a Hydraulic Press: Stroke, Daylight, Tonnage, Temperature, and Platen Size
When a new press project starts, one of the most common mistakes is treating the specification like a list of disconnected numbers. A team asks for tonnage, stroke, platen size, and temperature range, but nobody steps back and answers the bigger question first: what does this press actually need to do in production? That is where…
